Stands for Team Fortress Classic, an online gaming mod for Half-Life. Teams are typically made up of players from nine classes (scout, sniper, soldier, demo man, heavy-weapons guy, pyro, medic, engineer and spy), and are pitted against each other in various missions, from capture-the-flag to eliminate-the-hunted.

Everything about the game is ancient, yet its replayability, fun factor, and absolute insanity are undeniable. TFC is a refreshing change from such 'serious' mods as Counter-Strike and Day of Defeat.

I stayed up till 2:00 AM last night playing Murderball on Team Fortress. Fun times.

Team Fortress Classic is the 1999 update to the popular 1996 mod for Quake. It launched Half-Life's multiplayer features into the stratosphere, complimenting the amazing single-player experience with an equally superb multiplayer one. Some see it as a stop gap until Team Fortress 2, others as a testing ground to try new features which may or may not appear in this long awaited title. Others simply play it for what it is. Either way, it too is a hugely enjoyable mod with a healthy number of supportive servers and the backing of Valve Software.

T.F.C. or Token Fat Chick- The token fat girl that is always in a sorority in order to make the others girls seem more attractive by comparison. The T.F.C. also accompanies the other members of the sorority to parties and dance clubs and acts as the grenade.

Guy #1: "Dude the girls from the sorority just got to my party!"

Guy #2: "Good luck hooking up with any of them they brought along the T.F.C. and she's mastered the art of cock-blocking"

TFC stands for "Thanks For Calling." Used sarcastically to indicate to a friend that they excluded one from a social event or gathering.

For example, if a friend on Facebook posts a picture of themselves at the amusement park, one may comment "TFC" to indicate that one would have liked to join. In some cases it is nearly impossible for one to join should the event be out of town or country or sometimes it can make no sense at all because the friend may have even called to invite the person but the person could not make it due to their prior engagements. This is how it brings in some humor and sarcasm.
